I wrote BlackWatch because none of the screen savers which were available at the time did just what I wanted. Feature-packed screen savers tend to want plenty of RAM, CPU cycles, and disk space, and they patch a lot of operating system routines in order to work. On the other end, bare-bones screen savers don't provide the ability to securely lock your screen with password protection. Also, most screen savers of both types are implemented as system extensions, so you have to reboot your machine to run them or to get rid of them. That isn't optimal if you want to install a screen saver on a networked Macintosh which is busy acting as a server. BlackWatch solves these problems. It's small, quick, simple, compatible, and it's free.
